I have had no luck finding the episode or the dogs name..
But when I did a search for the problem they mentioned getting another dog to help. I wonder if they know someone with a dog that has a good temperament and around the same size that they could maybe test out for a short period of time and see if it helps at all? I know that its going out on a limb and the husband may not even want that to be an option but run it by them see if its a possibility.
I will continue in my efforts to find the info.
